Curcumin to Prevent Complications After Elective Abdominal Aortic Aneurysm (AAA) Repair

March 6, 2017 updated by: Amit Garg, Lawson Health Research Institute

Curcumin to Prevent Perioperative Complications After Elective Abdominal Aortic Aneurysm Repair: a Randomized Controlled Trial

The purpose of this program of research is to determine whether curcumin, a natural health product, can prevent acute kidney injury and other complications after elective AAA repair. If proven safe and effective, curcumin is an inexpensive intervention which can be readily applied to almost 50,000 AAA repairs performed worldwide each year. New knowledge about this intervention may also guide its use in other surgical and medical settings to prevent complications to the kidneys, heart and other organs.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

An abdominal aortic aneurysm (AAA) is a ballooning of the abdominal aorta, the major blood vessel of the body. AAA occurs in up to 2% of adults. Surgeons will plan an AAA repair when the aneurysm grows bigger than 5.5cm, because the AAA might burst without repair. Over 47,000 AAA repairs are performed each year. Despite the benefits of AAA repair there are risks, and the kidneys can be severely injured. We will test whether the natural health product curcumin has an effect on biomarkers of inflammation, kidney injury and heart injury from AAA repair. Curcumin appears to fight oxidation and inflammation, which are ways that the body can be injured by surgery. We will study 600 patients who have elective AAA repair. The patients will receive either curcumin or a matching placebo. We will recruit the 600 patients from 10 centres in Ontario. This study will help us determine whether curcumin exerts any biological effect on biomarkers and whether it is well tolerated. If there is evidence of beneficial effects in this 600 patient trial, this will justify a future larger trial to assess the effects of curcumin on outcomes most important to patients, families and their healthcare providers.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
